Answer:
20% increase
Step-by-step explanation:
Percent increase = (difference) / original *100 percent
= (12-10)/10 * 100percent
= 2/10 *100 percent
= 1/5 * 100 percent
=.2 * 100 percent
= 20%

Answer:</h2>
<u>The cost would be </u><u>$15.86</u>
<h2>
Step-by-step explanation:</h2>
The cost of 1 steak is $6.10
The cost of 2 3/5 steaks will be
Cost of 2 3/5 steaks = 6.10 * 2 3/5
Cost of 2 3/5 steaks = $15.86
The volume within the spherical compression wave increasing in t = 4 seconds is:64000000π cubic ft/sec.
<h3>
Volume of a sphere</h3>
Given:
dr/dt=100 ft/sec
When: t=4 seconds, radius(r)=400ft
Hence:
Volume of a sphere (V)=4/3πr³
dv/dt=4/3π.3r² dr/dt
dv/dt=4πr²dt/dr
When t=4 seconds
dv/dt=4π×(100×4)²×100 cubic ft/sec
dv/dt=4π×(400)²×100 cubic ft/sec
dv/dt=64000000π cubic ft/sec
Therefore the volume within the spherical compression wave increasing in t = 4 seconds is:64000000π cubic ft/sec.
